IMPROVEMENT IN RABBET-PLANES.

Specification forming part of Letters Patent No. 128,470, dated July 2,1872.

To all whom it may concern:

Be it known that I, Gnonen M. DARLEY, of Nebraska City, county of Otoeand State of Nebraska, have invented a new and Improved Rabbet-Plane;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingmaking part of this specification, in which Figure 1 is a front view ofthe plane. Fig. 2 is a bottom view of the plane. Fig. 3 is a sectionthrough dotted line :0 :r. Fig. 4 is a section through dotted line 3 y.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an improved plane, which is designed forrabbeting circular as well as oval work. It consists in the combinationof adjustable gauges with a plane, as will be hereinafter explained.

The following description of my inventionwill enable others skilled inthe art to understand it. i

In the accompanying drawing, A represents the stock of the plane, whichmay be made of any desired length, and which is curved on top at itsends so that it can be conveniently grasped in the hands. This stock Ais centrally throatcd to receive the plane-iron c and wedge d, andbeneath this throat the sole or face B of this plane is secured in asuitable manner. This sole presents a convex surface, which is below thecorresponding surface of the stock. It is convex transversely, and itsends extend out from the front and back sides of the stock A, as shownin Figs. 2, 3, and 4. The front projecting end of the sole B issustained against undue strain by a shoulder, a, which is formed on thestock A. On each side of the sole B is a gauge, 0, the wearing face ofwhich is protected by metal. Each gauge 0 is adjustable endwise, and isapplied to the stock A by means of dovetail tenons s 8, shown in Fig. 3.Each gauge is slotted longitudinally, as shown at g, which slot receivesthrough it a set-screw, h, which is tapped through a plate, 1), on thebottom of the stock,- and serves to fix the gauge at any desired point.Instead of a set-screw, h, a bolt may be used for each gauge 0, whichwill pass vertically through the stock A and receive on its upper end anut.

It will be seen from the above description that I have a right and lefthand rabbetingplane, which can be adjusted for any desired width ofrabbet by means of the gauges O, and which is adapted for all kinds ofcircular or oval Work.

Having described my invention, what I claim as new, is

The centrally-throated stock A, with its depressed sole B, incombination with the adjustable gauges G G, substantially as described.
